How did you setup your users?
When you setup EPESI you create the first company and the first contact. This is your company and you. You are given superadmin rights. You have access to everything. Then you create more users with different kind of levels. Next down is admin, then Manager then Employee. Employees can have quite restricted rights. This could be the only logical reason that you don't see something.
So the question is? What version are you running. What does not work - superadmin level?
Did you do anything with default setup? Did you change something?
What access level does have the second user?
This problem should be resolved to get to the bottom of the problem. But my question is why did you create for yourself superadmin account separate from the "normal" one? There is no need to have a separate account. You can use the same. If you think in Linux terms is like having "su" under Menu: Adminstrator. It is more convenient.
